WebJun 8, 2024 · Base flow: To varying degrees, the water in streams has a sustained flow, even during periods of lack of rain. Much of this "base flow" in streams comes from groundwater seeping into the bed and banks of the stream. Soil characteristics: Some soils, such as clays, absorb less water at a slower rate than sandy soils. WebMay 20, 2024 · Erosion by Water. Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
